Sash windows and sash doors have the advantage over doors and Windows on hinges that they when open take up less space. Yet they have aV drawback, it is not easy to get them tight. v' The present invention is a device adapted to beapplied to sash doors and sash -windows in order to secure complete tightness when the respective door or window is shut.

Figure 1 showsa double-Window in front view, and j Figure 2 is a horizontal cross section of the same.

Figures 3-8 show details. f

The frame 1 in which the Window is to be located is provided with rebates turned inwards, and it is on one side provided with a slit for letting through the sash window when opening it. The rebates of the Jframe `lie at such a distance from each other that the space between them is larger than the thickness of two Window sashes 2." If the sashes 2 are pressed together they may be slid laterally into an intermediate space 3 provided in the wall. If the .window is to Ybe shut it is slid into the window opening. It the sashes are then separated they are pressed against the respective frame rebates which, if desired, may be provided with tightening lists 4 `of rubber, felt or the like.

This separation of the sashes may be efected by a device according to Figure 3. 5 is a disk or pulley provided With two pegs 6 one of which is leftand the other righthanded. The pegs 6 are threaded into nuts 7 disposed on the respective sashes 2. If the disk 5 is turned in one direction and thus also the pegs 6 the sashes approach each other, ybut if the disk is turned in the other direction they are separated. f

On the sashes 2, Figure 1, is located a number of separating devices 8 according to Figure 3. In order to eect a simultaneous turning of the disks 5 a wire or rope 9 is located in a groove in the disks said rope embracing all the disks and in some way or other being secured in the vrespective disk so that it cannot glide on the same.

If one of the disks 5 is turned the remainingdisks are forced bythe rope 9 to turn too.

One Yof the pegs A6 is elongated and provided with a handle l0 in order to effect `a turning of the disks 5. f

'Thewvindow may be suspended in the frame in the same way as a common sash Window, that Vis to say it may be suspended in pulleys running on a rail or the like, or it may with or without pulleys stand on the lower portion of the frame, or on an intermediate portion, vor it may be suspendedby any suitable means.

One frame rebate is formed by a list or board which is removably secured to the frame or the Wall by means of screws vor suitable mountings. When it is desired to remove the sashes in order to put in a new pane or to clean them, it is only necessary to remove the detachable rebate.

Some details may be carried out in another way without changing the principle. If the invention is to be applied 'to .a part consisting of several window openings space for sliding the slidable sashes may be obtained by disposing the two adjacent sashes forming a stationary double-window at the necessary distance from each other.

Turning of the pegs 6 may also be eected by tie rods secured to the disks 5 or to levers located on the pegs 6, and motion of the rope 9 or of the tie rods mentioned above may also be effected by a handle which does not stand in a direct connection to any sepagating means, or by means ofy a slidable han- Figure 4 shows al separating device some- What deviating from the one described above. l1 is a ,disk provided with abutments 12. On the sashes 2 are located plates 13 one of which is provided With a; peg 14 running through holes' of the disk 11 as well as of the other plate 13, the sashes 2 being thus steadily lheld `in front of each other. The plates 13 are provided with recesses 15 into which the abutments 12 may sink down when the disk 1l is turned to a suitable position. If the disk is turned from this position the sashes are separated. Yet this device is not capable of approaching the sashes, and therefore it is suitable to provide springs between the sashes in order to effect their approaching. V

These separating means may be manipulated pair.

inthe same way as the devices according to Fi ure 3.

nother'embodiment consists of the one last described, but so to speak in a reversed manner, that is to say springs are disposed in order to separate the sashes from each other, but this can take place only by sub-- stituting an approaching mechanism for the separating mechanism.' An advantage offered by this arrangement is also that a ver'- tically slidablewindow by means of a suit.-V

abl constructed approaching mechanism can be roughtvto stop ,automatically in all ver-t tical positions (for instance if one happensl tolet loose the handle whenmanipulating n the device) 'f one sash. The links 21 may for example be four, one in each corner of the sash If Vthe lever 19 is turned according to the arrow the leverf19and the links 21 may n if the suspension of the sashes is arranged in a suitable manner turn round the geometricalr centres 22 whereby the sashes move toward each other. Y

Figuref': 23 is a laterally disposed peg secured in one sash. In the other sash is provided a hole to match or a packing box 24. v25 is an'eccentric device or crank at the turning of which in one or the other direction the ysashes may be slid laterally relatively to each other, and thus the sashes, due tothe oblique position of the peg 23,'will also movel toward and away from each other respectively. The sash pair is preferably provided with a peg and a hole respectively in each corner. y v

Figure 8 shows an embodiment according to a principle similar to the one shown in Figure 7. The sashes are brought to slide laterally relatively to each other by means of a crank or an eccentric whereby the sashes will move toward and away from each other respectively due to the laterally disposed resting surface along which the sashes abut on each` other. vThrough guides 26 and grooves 27 respectively the sashes are held closey to each other during the motion. The bevalling ofthe mutual resting surfaces of the sashes shown in the' figure only occurs at the side portions, and at the upper and lower portions Vrespectively of the sash pair.

' The construction shown 1n Figure 8 .may be slmplled so as to consist of for instance Leashes awayfrom the plane of the other sash respectively, while the other sash remains unmovable in the said direction. For this purpose the k'frame portion adjacent to the lastmentioned sash must be made smooth, that is to say without 1rebate in order to enable the slidingV of the sash pair when opening and shutting they Window.r Y Said arrangement might facilitate the suspension of the sash any.; l ,l y.

f Further the inwardly turned edges of two frame portions maybe made Awithout rebate which involves the practicaladvantage that the motion which the sashes must carrypout relatively vto eachtotherr in-order to bei slid freely into arecess in a wallV or between a pair of a jacent stationary sashes may be reduced toaminimum. 1 f The devices described above may be used in windows adapted to be slid horizontallyas yvlllias'vertically, and also in doors andthe In doors it is unsuitable to use a divided framebottom portionas one does not wish to have a groove therein. Figure 5 shows a device in which tightenin between a 'door and a plain bottom piece or oor may be produced. 16 is a list the upper surface of which slants laterally inwards. The frames 17 of the door are bevelled to match. When the frames are separated the list 16 isY pressedytoward the ioor or the lower.y rtion 18 of the frame. When the frames 1 are moved toward each other the list 16 may be raised, and thus the door .andthe list may easily be slid sidewards. Raising of the list 16 may suitably be effected by springs disposed between the list and the door frames. Y yIn order to lock a door ory window it is enough to lock the handle manipulating the separating means.

The application of the invention to doors and windows with simple frames and sashes respectively mayftake place in such a way that in the constructions described aboveone frame` and sash respectivel is substituted for by a blind frame and blin sash respectively.

It is also possible to reduce the blind frame or sash only to an upper vand lower portion andthe two lateral portions respectively. f' v vHaving now described our invention, what -we'claimas new and desire to secure by'Letters Patent is:
